[WIP] Adding support for subcollections and related subresources

[abellotti]

Adding support for subcollections and related subresources

• Dynamically driven by the "subcollections" exposed via OPTIONS /api/:collection

• supports queries and actions

  Queries: miq.vms.find(166).tags.collect(&:name) miq.vms.find(166).tags.select(:categorization).collect(&:categorization)

  Subcollection Actions: miq.vms.find(166).tags.assign(:name => "/managed/location/ny") miq.vms.find(166).tags.assign([{:name => "/managed/location/chicago"}, {:name => "/managed/cc/001"}])

  Subcollection resource actions: miq.vms.find(166).tags.find(32).unassign miq.vms.find(166).tags.where(:name => "/managed/location/*").collect(&:unassign)

  Nested searches with sub resource actions: miq.providers.find_by(:name => "test-vc").vms.where(:name => "testvm-*").last.tags.where(:name => "environment/testing").unassign

  Fixes: #31 Fixes: #32
